keyord in original post was: "aluminum breed material"
I kind of grasped his concept but I don't think materials are available yet. I think that he is talking about colapsible water jug made out of metal. Bottom will be outlined with a metal ring in order to stabilize the jug on the hot plate or ground and top with have another metal ring that will make structure more sturdy and serve as a flow regulator or stopper holder. Good concept yet on the heavy side.
